Abstract
An electric working machine in one aspect of the present disclosure includes an output shaft, a motor, a housing, an acceleration detector, a twisted motion detector, a reference level changer, and a motor controller. The acceleration detector detects an acceleration of the housing in a circumferential direction of the output shaft. The twisted motion detector detects a twisted motion of the housing based on a reference level and the acceleration detected. The reference level determines that the housing is twisted. The reference level changer changes the reference level based on a rotating motion of the output shaft.
